Methods: Experts were invited to participate in a modified Delphi consensus process.

Identification of Missense Extracellular Matrix Gene Variants in a Large Glaucoma Pedigree and Investigation of the N700S Thrombospondin-1 Variant in Normal and Glaucomatous Trabecular Meshwork Cells.

Purpose: Primary open-angle glaucoma (POAG) is a complex heterogeneous disease. While several POAG genes have been identified, a high proportion of estimated heritability remains unexplained. Elevated intraocular pressure (IOP) is a leading POAG risk factor and dysfunctional extracellular matrix (ECM) in the trabecular meshwork (TM) contributes to elevated IOP.

Electron Beam Irradiated Corneal Versus Gamma-Irradiated Scleral Patch Graft Erosion Rates in Glaucoma Drainage Device Surgery.

Introduction: Patch graft erosion and implant exposure is a known complication of glaucoma drainage device (GDD) surgery. Recently, electron beam (e-beam) irradiated corneal tissue ha s become available; however, limited data exist on the rates of erosion for e-beam irradiated corneal grafts compared to traditional scleral grafts after GDD surgery.

Methods: This retrospective study examines the records of 253 eyes from 225 adult subjects who underwent GDD surgery with either e-beam irradiated corneal or scleral grafts at the Casey Eye Institute by five surgeons between April 22, 2014 and October 11, 2017.

Proptosis masquerading as buphthalmos following glaucoma drainage device surgery in a child with congenital glaucoma.

Glaucoma drainage devices are commonly used in the surgical treatment of children with glaucoma. We report a case of unusually large reservoir formation causing proptosis, exposure keratopathy, and motility deficits. This case highlights the importance of B-scan and axial length measurements in differentiating proptosis from buphthalmos in children with glaucoma.

Ex-PRESS Miniature Glaucoma Shunt Versus Ahmed Glaucoma Valve in the Surgical Treatment of Glaucoma in Pseudophakic Patients.

Purpose: The aim of this study was to compare the 3-year outcome of Ex-PRESS miniature glaucoma shunt versus Ahmed glaucoma valve in pseudophakic patients.

Patients And Methods: We retrospectively reviewed the records of patients with a history of clear corneal phacoemulsification alone, or failed trabeculectomy following phacoemulsification, who subsequently underwent Ahmed glaucoma valve (AGV) implantation or Ex-PRESS shunt surgery. The main outcome measure, surgical success, was defined as an intraocular pressure between 5 and 21 mm Hg and a 20% intraocular pressure reduction from baseline (with/without glaucoma medications) without glaucoma reoperation.

Ophthalmic imaging in children: current practice patterns and perceived barriers.

Pediatric ophthalmologists were surveyed to determine current practice patterns regarding ophthalmic imaging for children and to identify perceived barriers to the adoption of imaging technologies in their practices. Some form of imaging was available in the majority of practices (94%), but its use varied widely among different clinical scenarios. The two most frequently perceived barriers to performing imaging in children were cooperation and lack of sufficient data supporting ophthalmic imaging in clinical practice.

Effectiveness of a Retention Program to Improve Performance During the First Semester of a Doctor of Physical Therapy Program.

Background: To meet the expanding need for physical therapists universities are under increasing pressure to enroll, educate, and train physical therapists. Poor academic performance can result in student dismissal from a physical therapy program. The purpose of this study is to determine if implementation of a retention program would improve student academic performance in the foundational science curriculum in a physical therapy program.

Projection-Resolved Optical Coherence Tomography Angiography of Macular Retinal Circulation in Glaucoma.

Purpose: To detect macular perfusion defects in glaucoma using projection-resolved optical coherence tomography (OCT) angiography.

Design: Prospective observation study.

Participants: A total of 30 perimetric glaucoma and 30 age-matched normal participants were included.

Combined Glaucoma Tube Shunt (Ahmed) and Fluocinolone Acetonide (Retisert™) Implantation Compared to Ahmed Alone in Uveitic Glaucoma.

Introduction: Glaucoma is a known complication of uveitis, and may require glaucoma tube shunt implantation for intraocular pressure (IOP) control. The success of glaucoma tube shunt implantation in the setting of a local ocular steroid depot in uveitic glaucoma remains unknown. The purpose of this study was to determine whether patients who underwent combined glaucoma tube shunt (Ahmed) and fluocinolone acetonide (Retisert™, Bausch + Lomb, Bridgewater, NJ, USA) implantation have superior outcomes compared to patients with Ahmed implants only in the setting of uveitic glaucoma.

Optical Coherence Tomography Angiography of the Peripapillary Retina in Glaucoma.

Importance: Vascular factors may have important roles in the pathophysiology of glaucoma. A practical method for the clinical evaluation of ocular perfusion is needed to improve glaucoma management.

Objective: To detect peripapillary retinal perfusion in glaucomatous eyes compared with normal eyes using optical coherence tomography (OCT) angiography.

Relationships of Preharvest Weather Conditions and Soil Factors to Susceptibility of Sweetpotato to Postharvest Decay Caused by Rhizopus stolonifer and Dickeya dadantii.

Postharvest soft rots of sweetpotato caused by Rhizopus stolonifer (Rhizopus soft rot) and Dickeya dadantii (bacterial root rot) occur sporadically and can result in significant losses. A 3-year field study related preharvest conditions, including soil texture, chemistry, and fertility; air temperature; soil temperature and moisture; and various cultural practices (153 total variables), to postharvest susceptibility to both diseases in 75 sweetpotato fields in North Carolina and 63 sweetpotato fields in Louisiana. Storage roots were sampled from each field, cured, stored, and inoculated with each pathogen after 100 to 120 days in storage.

Student perceived competence in direct access to physical therapy in a doctor of physical therapy program at a historically black university.

Physical therapists provide care via direct access in many states. Greater perceived competence with direct access among graduating physical therapists is critical. The purpose of this study was to assess student physical therapists' perceived competence with direct access.

Childhood glaucoma surgery in the 21st century.

Most children with glaucoma will require surgery in their lifetime, often in their childhood years. The surgical management of childhood glaucoma is however challenging, largely because of its greater potential for failure and complications as compared with surgery in adults. The available surgical repertoire for childhood glaucoma has remained relatively unchanged for many years with most progress owing to modifications to existing surgery.

Respiratory complications associated with ketamine anesthesia for ophthalmic procedures following intraocular pressure measurement in children.

Background: We compared respiratory complications (RCs) in children who received intramuscular (IM) versus intravenous (IV) or no ketamine for intraocular pressure (IOP) measurement to test our observation that IM ketamine is associated with higher incidence of RCs.

Materials And Methods: We analyzed 149 eye examinations under anesthesia with ketamine in 27 patients and 263 non-ketamine examinations under anesthesia in 81 patients using a mixed effects logistic regression model.

Results: IM KETAMINE WAS STRONGLY ASSOCIATED WITH INCREASED ODDS OF RCS COMPARED TO NO KETAMINE (ODDS RATIO (OR): 20.

Effect of genotype on chemical composition, ruminal degradability and in vitro fermentation characteristics of maize residual plants.

The objective of this study was to determine the changes to residual plant feeding value of early- and late-maturing maize varieties. The influence of the cell wall carbohydrate composition, in terms of neutral and acid detergent fibre (NDF and ADF) content, NDF and dry matter (DM) degradability, and in vitro organic matter digestibility and gas production on the feeding value of a range of maize genotypes, was measured. The different genotypes were allotted into two maturity groups (MG I--early to mid-early: S210-S240; MG II--mid-late to late: S 250-S280) and harvested at four different harvest dates (depending on the DM content of the kernels).
